The unit rate of the relation will be 35 miles per gallon.
Step-by-step explanation:
The slope of a graph, the constant of proportionality of an equation and the rate of change are all similar terms and means the same.
Now, given that a graph has a constant of proportionality of 35 and here y represent miles and x represents gallons.
Therefore, the unit rate of the relation will be 35 miles per gallon. (Answer)
